Question 900169: Consider a class of 4 students, 2 boys and 2 girls. Suppose that these students will be grouped into two teams of equal size. Assuming that the teams are selected at random, determine the probability that there is one all-boy team and one all girl team. Explain. Answer by Edwin McCravy(20054) (Show Source):
There are only 3 ways to split them:
1. {B1, B2} and {G1, G2}
2. {B1, G1} and {B2, G2}
3. {B1, G2} and {B2, G1}
Only case 1 is one 2-boys team and one 2-girle team.
That's 1 out of 3, so the probability is 1 over 3 or
